Description

  The present invention relates to a broadcast receiving device mounted on a mobile body and a processing method in the broadcast receiving device.

  Conventionally, a digital broadcast receiver described in Patent Document 1 is known. In this digital broadcast receiver, scan processing is executed based on a scan instruction, and a channel list of broadcast stations that can be received by the tuner is created. The created channel list is associated with position information of the point where the channel list is created, and a channel list corresponding to the current position of the digital broadcast receiver is displayed on the display unit. A desired channel can be selected from the channel list displayed on the display unit. With such a digital broadcast receiver, even if the broadcast stations that can be received change while moving, a channel list that represents broadcast stations that can be normally received can be obtained.

  However, in such a digital broadcast receiver, a channel list that can be received corresponding to a plurality of areas has to be stored in a memory or the like in advance, and there is a disadvantage that a large storage capacity is required. is there. In addition, it is impossible to cope with a change in broadcasting station, a change in frequency allocated to the broadcasting station, and the like.

JP 2009-111602 A

  Therefore, when the reception level of the broadcast signal from the selected broadcast station is reduced (reception field reduction), it is possible to automatically search for a selectable broadcast station (scan process) and select that channel. It is conceivable to preset (set) a broadcast station in a broadcast receiving apparatus (auto-select processing). However, when the reception level of the broadcast signal from the selected broadcast station is reduced, if the autoselect process is automatically executed, the reception level of the broadcast signal from the selected broadcast station is Even if the sound quality deteriorates due to the deterioration, it is unwilling for the user who still wants to listen to the received broadcast program. In addition, when moving in an area where the reception quality of broadcast signals from each broadcasting station is unstable, such as when moving around a building, the autoselect process is frequently performed, and the user may feel annoyed. .

  The present invention has been made in view of such circumstances, and a broadcast receiving apparatus capable of performing autoselect processing at a timing according to the user's intention without particularly requiring a large amount of storage capacity, and A processing method in the broadcast receiving apparatus is provided.

  A broadcast receiving apparatus according to the present invention is a broadcast receiving apparatus mounted on a mobile body, and when a predetermined operation is performed, searches for a selectable broadcast station and selects the selectable broadcast station. First autoselect execution means for performing autoselect processing for setting, and device status information representing the status of the broadcast receiving device when the autoselect processing is performed by the first autoselect execution means is stored in the storage unit First apparatus status information storage control means, apparatus status determination means for determining whether or not the broadcast receiving apparatus is in a situation represented by the apparatus status information stored in the storage unit, and the apparatus status determination When the means determines that the broadcast receiving apparatus is in a situation represented by the apparatus status information, the broadcast receiving apparatus has a second autoselect executing means for performing the autoselect process.

  With this configuration, when a predetermined operation is performed by the user, an auto-select process for searching for a selectable broadcast station and setting the selectable broadcast station is performed. The device status information representing the status of the broadcast receiving device that moves with the moving body is stored in the storage unit. Then, when the broadcast receiving apparatus that moves together with the mobile body is in a situation represented by the apparatus status information stored in the storage unit, the autoselect process is executed regardless of the predetermined operation.

  In the broadcast receiving apparatus according to the present invention, the apparatus status information includes position information indicating a position of the broadcast receiving apparatus that moves together with a moving body, movement direction information indicating a moving direction of the broadcast receiving apparatus, and the broadcast receiving apparatus. It can be set as the structure containing the broadcast station information showing the broadcast station currently selected.

  With such a configuration, the position of the broadcast receiving device that moves together with the mobile body, the moving direction of the broadcast receiving device, and the broadcast station that is selected by the broadcast receiving device are stored as device status information in the storage unit. If it matches the stored one, the autoselect process is performed regardless of the predetermined operation.

  In the broadcast receiving apparatus according to the present invention, a broadcast station selected from the broadcast station set by the autoselect process performed by the first autoselect execution unit is selected immediately before execution of the autoselect process. The same station determining means for determining whether the broadcasting station is the same series as the broadcasting station, and the first device status information storage control means is set by the auto-selection process by the same affiliate station determining means. When it is determined that a broadcast station selected from the selected broadcast station is a broadcast station of the same series as the broadcast station selected immediately before execution of the autoselect process, the device status information is stored in the storage station. The configuration can be stored in the unit.

  With such a configuration, a broadcast station actually selected from the selectable broadcast stations set by the autoselect process executed based on a predetermined operation by the user is selected before the autoselect process is executed. In the case where the broadcasting station is the same series as the broadcasting station, the apparatus status information when the autoselect process is executed is stored in the storage unit. Then, when the broadcast receiving apparatus that moves together with the mobile body is in a situation represented by the apparatus status information stored in the storage unit, an autoselect process that is executed without performing a predetermined operation is performed. Thereby, when the broadcast receiving apparatus is in a certain situation (for example, a situation specified by a position, a moving direction, and a selected broadcast station), a broadcast station of the same series is selected by auto-select processing. For users who have become a habit, auto-select processing will be executed at a timing according to their will.

  In the broadcast receiving apparatus according to the present invention, the apparatus status information includes position information indicating a position of the broadcast receiving apparatus that moves together with the mobile body, and is set in association with an area in which the broadcast receiving apparatus moves, The autoselect process counting means that counts up when the autoselect process is executed by the first autoselect execution means and the first apparatus status information control means have a predetermined number of times obtained by the autoselect process count means. When the value reaches the value, the apparatus status information can be stored in the storage unit.

  With such a configuration, when the number of times that the auto-select process based on a predetermined operation is performed when passing through a certain area, the broadcast receiving apparatus that moves together with the moving body indicates the position of the broadcast receiving apparatus. Device status information including position information is stored in the storage unit. When the broadcast receiving device that moves with the moving body moves in the area, the predetermined operation is performed when the status of the broadcast receiving device is represented by the device status information stored in the storage unit. Regardless of whether or not the auto-select process is executed.

  In the broadcast receiving apparatus according to the present invention, the timing at which the first device status information storage control unit stores the device status information in the storage unit, and the first device status information storage control unit stores the device status information in the storage unit. The apparatus status information acquisition interval measuring means for measuring the time between the timing stored in the storage unit last time and the time obtained by the apparatus status information acquisition interval measuring means is less than or equal to a predetermined time, the first The apparatus status information storage control means may include apparatus status information deleting means for deleting the apparatus status information previously stored in the storage section from the storage section.

  According to such a configuration, the autoselect process based on the predetermined operation is executed, and the apparatus status information at that time is again based on the operation of the predetermined process within a predetermined time after being stored in the storage unit. When the auto-select process is executed and the device status information at that time is stored in the storage unit, the device status information stored in the storage unit immediately before is deleted from the storage unit. When the broadcast receiving apparatus travels for a short time within a predetermined time together with the mobile object, it is assumed that the user performs an operation for auto-select processing when traveling in an area where the electric field strength is unstable. Can do. For this reason, by deleting the apparatus status information stored in the storage unit as described above, it is possible to prevent unnecessary autoselect processing from being repeated and to save the storage capacity of the storage unit.

  The broadcast receiving apparatus according to the present invention may include a second apparatus status information storage control unit that stores the apparatus status information in the storage unit based on a predetermined operation.

  With such a configuration, if it is known in advance what kind of situation (apparatus status information) the broadcast receiving apparatus that moves together with the mobile body should perform, for example, movement If it is known in advance that the broadcast reception device should be selected when the broadcast receiving apparatus moves with the body, the reception quality is reduced and the autoselect processing should be executed. Device status information (including position information and broadcast station information) can be stored in the storage unit.

  According to the broadcast receiving apparatus according to the present invention, the status of the broadcast receiving apparatus (represented by the apparatus status information) when the autoselect process is executed based on a predetermined operation performed by the user is stored. Then, when the broadcast receiving apparatus that moves together with the mobile body is in the stored state, the autoselect process is executed regardless of the predetermined operation. For this reason, there is no need for a storage capacity for storing in advance information on broadcast stations that can be selected in association with points, and the autoselect process can be performed at a timing according to the user's intention.

It is a figure which shows the example by which the navigation screen was displayed on the display part shown in FIG.

  An embodiment of the present invention will be described with reference to the drawings.

  A broadcast receiving apparatus according to an embodiment of the present invention is configured as shown in FIG. This broadcast receiving apparatus is an in-vehicle radio receiving apparatus that is mounted on a vehicle that is a moving body and receives AM and FM radio broadcasts.

  In FIG. 1, the in-vehicle radio receiver 100 includes a tuner 15, a demodulation circuit 16, an output circuit 17, and a speaker 18. The in-vehicle radio receiver 100 further includes a control unit 11, an operation unit 12, a display unit 13, and a storage unit 14. The tuner 15 receives a radio broadcast signal having a tuning frequency that is AM-modulated or FM-modulated. The demodulation circuit 16 demodulates the radio broadcast signal received by the tuner 15 to generate a radio reception signal that represents the actual broadcast content. The output circuit 17 processes the radio reception signal from the demodulation circuit 16 to generate an audio signal, and drives the speaker 18 according to the audio signal. Thereby, a sound based on the audio signal is emitted from the speaker 18.

  The control unit 11 executes various control processes in accordance with operations on the operation unit 12. The control unit 11 controls the tuner 15, the demodulation circuit 16 and the output circuit 17 to receive a radio broadcast signal and output an audio, and to search for a radio broadcast signal having a receivable tuning frequency as described later, In other words, an auto-select process for searching for a selectable broadcast station and presetting (setting) the selectable broadcast station in the apparatus is performed. A navigation device 19 is connected to the in-vehicle radio receiver 100, and the control unit 11 uses the vehicle position information representing the traveling position of the host vehicle from the navigation device 19 as information representing the position of the in-vehicle radio receiver 100. In addition, vehicle travel direction information representing the travel direction of the host vehicle can be acquired as information representing the travel direction of the in-vehicle radio receiver 100. The control unit 11 can further store various information generated by the control processing in the storage unit 14 and can display the information on the display unit 13.

  In a situation where a certain broadcast station is selected and audio output based on a broadcast signal from the broadcast station is made from the speaker 18, the control unit 11 executes autoselect processing according to the procedure shown in FIG.

  In FIG. 2, the control unit 11 determines whether or not an operation for executing the autoselect process has been performed on the operation unit 12 (S <b> 10), and the situation of the host vehicle, that is, the situation of the in-vehicle radio receiver 100 (specifically, The travel position, the travel (moving) direction, and the currently selected broadcasting station) match the situation represented by the vehicle situation information (device situation information) stored in the storage unit 14 as will be described later. (S15, S16, S17: device status determination means). In the process, for example, the reception quality of the broadcast signal from the currently selected broadcast station deteriorates and it becomes difficult to listen to the sound of the broadcast program. When an operation for executing the autoselect process is performed (YES in S10), the control unit 11 executes the autoselect process (S11: first autoselect execution means). In this auto-select processing, the tuning frequency in the tuner 15 is sequentially changed to search for a selectable broadcast station, and the selectable broadcast station is set. Specifically, information (for example, tuning frequency) that specifies the broadcast stations that can be selected is set as a list.

  For example, the control unit 11 that has executed the autoselect process displays a selection screen for registration of vehicle status information (device status information) as shown in FIG. 3 on the display unit 13 (S12), and registers the vehicle status information. Is selected (S13). When the user selects the registration by operating the “YES” button on the vehicle status information registration selection screen (see FIG. 3) displayed on the display unit 13 (YES in S13), the control unit 11 Acquires the vehicle position information representing the traveling position of the host vehicle and the vehicle traveling direction information representing the traveling direction of the host vehicle from the navigation device 19, and the broadcasting station currently tuning the vehicle position information and the vehicle traveling direction information. Is stored in the storage unit 14 as vehicle status information (device status information) indicating the status of the vehicle (the status of the in-vehicle radio receiving device 100 that moves together with the vehicle) (S14: first device status information storage control). means). These vehicle position information (latitude and longitude, etc.), vehicle travel direction information (east, west, north and south, etc.) and broadcast station information (broadcast station name, tuning frequency, etc.) are stored in a vehicle status information registration table as shown in FIG. 14 is stored.

  Thereafter, the control unit 11 executes a process (S19) for actually selecting a broadcast station from the selectable broadcast stations set by the auto-select process (S11). Even if the process related to the channel selection of the broadcast station automatically selects, for example, a broadcast station corresponding to the maximum or minimum tuning frequency from the set broadcast stations that can be selected, the user A broadcast station may be selected based on the operation of the operation unit 12. Through the processing related to the channel selection, audio output based on a broadcast signal from a new broadcast station with good reception quality is made from the speaker 18.

  When the user selects not to register the vehicle status information by operating the “NO” button on the vehicle status information registration selection screen (see FIG. 3) displayed on the display unit 13 (S13). NO), the control unit 11 selects a broadcast station from the selectable broadcast stations set by the autoselect process (S11) without executing the process (S14) for registering the vehicle status information described above. The process (S19) for performing is performed.

  As described above, whether or not the operation unit 12 has been operated to execute the autoselect process (S10), and the situation of the host vehicle (specifically, the travel position, the travel direction, and the current channel selection) In the process of monitoring whether or not it matches the situation represented by the vehicle situation information stored (registered: see FIG. 4) in the storage unit 14 (S15, S16, S17). When the vehicle situation matches the situation represented by the vehicle situation information already stored in the storage unit 14 (YES in S15, YES in S16, YES in S17), the control unit 11 executes auto-select processing (S18). : Second auto-select execution means). Specifically, each of the vehicle position information and the vehicle travel direction information acquired from the navigation device 19 matches that stored in the storage unit 14 (YES in S15, YES in S16), and is currently selected. Is the same as the broadcast station specified by the broadcast station information stored in the storage unit 14 (YES in S17), the autoselect process (S18) is automatically executed regardless of the operation on the operation unit 12. Is done. Then, the control unit 11 executes a process (S19) for broadcasting from a selectable broadcast station set by the auto-select process, and based on the broadcast signal from the newly selected broadcast station. Audio output is made from the speaker 18.

  Thereafter, in the same manner as described above, the auto-select process is executed based on the operation on the operation unit 12 (YES in S10, S11) for storing (registering) the vehicle status information in the storage unit 14. Processing (S12 to S14) is executed. Then, every time the host vehicle is in a situation represented by the vehicle situation information stored in the storage unit 14 (NO in S10, YES in S15, YES in S16, YES in S17), the operation on the operation unit 12 is performed. Regardless, the autoselect process is automatically executed (S18). Then, audio output is performed based on the broadcast signal from the broadcast station selected from the broadcast stations set by each autoselect process (S19).

  In the in-vehicle radio receiving apparatus 100 as described above, the situation of the own vehicle when the autoselect process (S11) is executed based on the operation of the operation unit 12 performed by the occupant (user) intention, that is, Vehicle status information (apparatus status information) indicating the status of the in-vehicle radio receiving device 100 (vehicle running position (position), vehicle running direction (moving direction), selected broadcasting station) is stored. When the in-vehicle radio receiving device 100) that moves with the host vehicle is in a situation represented by the stored vehicle status information (device status information), it is automatically selected regardless of the operation at the operation unit 12. Processing is executed. For example, as shown in FIG. 4, when the vehicle status information is stored in the storage unit 14, the host vehicle once changes the point P1 (X1, Y1) to the northeast while the in-vehicle radio receiving device 100 selects the ABC station. If auto-select processing based on the operation of the operation unit 12 is performed in a situation where the vehicle travels in the direction, the vehicle-mounted radio reception device 100 selects the ABC station again while the vehicle-mounted radio reception device 100 selects the point P1 (X1, Y1). When traveling in the northeast direction, it is assumed that the reception quality of the broadcast signal from the ABC station has deteriorated, and the autoselect process (S18) is automatically executed regardless of the operation at the operation unit 12.

  Thus, vehicle status information (vehicle position information, vehicle travel direction information, broadcast station information), that is, device status information is simply stored in the storage unit 14 (see FIG. 4), and tuning can be performed at each point. It is not necessary to secure a large amount of storage capacity in the storage unit 14 for directly storing information about a broadcasting station. In addition, the auto-selection process is automatically performed when the vehicle is in a situation where the auto-selection process that was once performed by the occupant (user) is performed. Auto-select processing can be performed at the same timing.

  The control unit 11 can perform autoselect processing according to the procedure shown in FIG. 5 instead of the procedure shown in FIG. This is when the broadcast station that was selected before the autoselect process and the broadcast station that was actually selected from the selectable broadcast stations set by the autoselect process were the same series, It is characterized by storing vehicle status information. In FIG. 5, the same step number as the step number shown in FIG. 2 indicates the same process.

  In FIG. 5, whether or not an operation for executing auto-select processing has been performed by the operation unit 12 (S10), and the situation of the host vehicle, that is, the situation of the in-vehicle radio receiver 100 (travel position (position), travel direction). Whether the (moving direction) and the currently selected broadcasting station match the situation represented by the vehicle situation information (device situation information) stored in the storage unit 14 (see FIG. 4) (S15). , S16, S17), if an operation for executing the autoselect process is performed (YES in S10), the control unit 11 broadcast station information indicating the currently selected broadcast station. After obtaining (S21), auto-select processing is executed (S11). Then, the control unit 11 performs a process for selecting a broadcast station designated by the operation of the operation unit 12 from the selectable broadcast stations set by the auto-select process (S22). Through the processing related to the channel selection, audio output based on a broadcast signal from a new broadcast station with good reception quality is made from the speaker 18.

  Thereafter, the control unit 11 determines whether or not the newly selected broadcast station is in the same series as the broadcast station (see S21) that was selected immediately before the execution of the autoselect process (S11). (S23: Same affiliated station determination means). If these broadcast stations are in the same series (YES in S23), the control unit 11 displays the vehicle status information registration selection screen (see FIG. 3) as described above (see FIG. 2). Is displayed (S12), and when the "YES" button is operated by the occupant (user) and registration is selected (YES in S13), vehicle status information (vehicle position information, vehicle travel direction information, broadcast station) Information) is stored in the storage unit 14 (S14: see FIG. 4).

  Note that the broadcast station selected from the selectable broadcast stations set in the autoselect process (S11) is not in the same series as the broadcast station selected immediately before the autoselect process (S11). In the case (NO in S23), or in the selection screen for registration of vehicle status information (see FIG. 3), when it is selected not to register the vehicle status information by operating the “NO” button (NO in S13), The control unit 11 ends the process as it is.

  Further, whether or not an operation for executing auto-select processing has been performed on the operation unit 12 (S10) and the situation of the host vehicle (travel position, travel direction, and currently selected broadcasting station) are stored in the storage unit. In the process of monitoring whether or not the situation represented by the vehicle situation information stored in 14 (see FIG. 4) matches (S15, S16, S17), the situation of the host vehicle is already stored in the storage unit 14. If it matches the situation represented by the vehicle situation information (YES in S15, YES in S16, YES in S17), the control unit 11 automatically executes auto-select processing as described above (S18). ). Then, one broadcast station is selected from the selectable broadcast stations set by the autoselect process (S19).

  In the in-vehicle radio receiving apparatus 100 that performs processing according to the procedure shown in FIG. 5, from a selectable broadcast station set by auto-selection processing that is executed based on the operation of the operation unit 12 by a passenger (user). When the broadcast station actually selected is a broadcast station of the same series as the broadcast station selected before the execution of the autoselect process, vehicle status information (vehicle position information, vehicle travel direction information, broadcast station) Information) is stored in the storage unit 14. When the vehicle is in a situation represented by the vehicle situation information stored in the storage unit 14, an auto-select process that is automatically executed without any operation on the operation unit 14 is performed. As a result, when the host vehicle is in a certain situation (for example, a situation specified by the traveling position, traveling direction, and selected broadcasting station), it is possible to select a broadcasting station of the same series by auto-select processing. For the user who has become a habit, auto-select processing is executed at a timing according to his / her intention.

  Further, the control unit 11 can perform the auto-select process according to the procedure shown in FIG. 6 instead of the procedure shown in FIGS. This is characterized in that, when the auto-select process is frequently performed, only the vehicle status information when the latest auto-select process is executed is held in the storage unit 14. In FIG. 6, the same step numbers as those shown in FIGS. 2 and 5 indicate the same processing.

  In FIG. 6, whether or not an operation for executing autoselect processing has been performed in the operation unit 12 (S10), and the situation of the own vehicle, that is, the situation of the in-vehicle radio receiver 100 (travel position (position), travel direction). (Moving direction) and the currently selected broadcasting station) monitor whether or not the situation represented by the vehicle situation information stored in the storage unit 14 matches (S15, S16, S17). If an operation for executing the auto-select process is performed in the process (YES in S10), the control unit 11 executes the auto-select process (S11), and then the same process as described above (S12 to S14). ), Vehicle status information (vehicle position information, vehicle traveling direction information, broadcast station information) is stored (registered) in the storage unit 14. Further, the control unit 11 acquires the time ti from the internal timer and stores (registers) it in the storage unit 14 in association with the vehicle status information (S31). The vehicle position information (latitude and longitude, etc.), vehicle traveling direction information (east, west, south, north, etc.) and broadcast station information (broadcast station name, tuning frequency, etc.) are stored in the storage unit 14 as a vehicle status information registration table as shown in FIG. In the vehicle status information registration table, the time ti when the vehicle status information is registered is associated with the vehicle status information (vehicle position information, vehicle travel direction information, broadcast station information).

  Thereafter, the control unit 11 refers to the vehicle situation information registration table (see FIG. 7A) stored in the storage unit 14 and the time ti acquired this time and the time ti− the previous vehicle situation information stored in the storage unit 14. The difference between 1 and the time between time ti and time ti-1 is calculated (apparatus status information acquisition interval measuring means), and it is determined whether or not the time is equal to or less than a predetermined time Δ (S32). When this time is larger than the predetermined time Δ (NO in S32), that is, when the vehicle status information is registered with a relatively long time interval, the vehicle status information stored (registered) in the storage unit 14 is retained as it is. . On the other hand, when the time is equal to or less than the predetermined time Δ (YES in S32), the control unit 11 deletes the previously registered (ti-1) vehicle status information and the time ti-1 (S33: device status information deletion). means). For example, in the vehicle situation information registration table shown in FIG. 7A, when the time between time t3 and time t4 is equal to or less than a predetermined time Δ, the vehicle situation information registered at time t3 (vehicle position information, vehicle travel direction information) , And broadcast station information) is deleted from the storage unit 14 (vehicle situation information registration table), and the vehicle situation information registration table is updated as shown in FIG. 7B.

  As described above, after the vehicle status information (device status information) is registered and deleted, the control unit 11 selects a broadcast station from the selectable broadcast stations set in the autoselect process (S11). The process (S19) for performing is performed. Then, audio output based on the broadcast signal from the selected broadcast station is made from the speaker 18.

  Further, whether or not an operation for executing auto-select processing has been performed on the operation unit 12 (S10) and the situation of the host vehicle (travel position, travel direction, and currently selected broadcasting station) are stored in the storage unit. In the process of monitoring whether or not it matches the situation represented by the vehicle situation information stored in FIG. 14 (see FIGS. 7A and 7B) (S15, S16, S17), the situation of the host vehicle is stored in the storage unit 14 (S15: YES, S16: YES, S17: YES), the control unit 11 automatically executes auto-select processing as described above. (S18). Then, one broadcast station is selected from the selectable broadcast stations set by the autoselect process (S19).

  In the in-vehicle radio receiving device 100 that performs processing according to the procedure shown in FIG. 6, vehicle status information (device status information) when the autoselect processing based on the operation at the operation unit 12 is executed is stored in the storage unit 14. When the vehicle status information (device status information) when the autoselect process based on the operation in the operation unit 12 is executed again within the predetermined time Δ after being stored is stored in the storage unit 14 immediately before. The vehicle status information (device status information) stored in the storage unit 14 is deleted from the storage unit 14. As described above, when the vehicle travels for a short time within the predetermined time Δ, the occupant (user) performs an operation for auto-selection processing. When the vehicle travels in an unstable region of the electric field strength. It can be assumed. For this reason, by deleting the vehicle status information (device status information) stored in the storage unit 14 as described above, it is possible to prevent unnecessary autoselect processing (S18) from being repeated, and the storage unit 14 Storage capacity can be saved.

  Further, the control unit 11 can perform auto-select processing according to the procedure shown in FIG. 8 instead of the procedure shown in FIGS. This is characterized in that the vehicle status information (device status information) is stored in the storage unit 14 only when the autoselect process is repeatedly performed in the same area. In FIG. 8, the same step numbers as those shown in FIGS. 2, 5, and 6 indicate the same processing.

  In FIG. 8, whether or not an operation for executing the autoselect process is performed in the operation unit 12 (S10), and the situation of the own vehicle, that is, the situation of the in-vehicle radio receiver 100, (travel position (position), travel Whether the direction (moving direction) and the currently selected broadcasting station match the situation represented by the vehicle situation information (device situation information) stored in the storage unit 14 (see FIG. 4) ( When an operation for executing the autoselect process is performed in the process of monitoring S15, S16, and S17 (YES in S10), the control unit 11 sends the travel position of the host vehicle (in-vehicle radio) from the navigation device 19. Vehicle position information representing the position of the receiving device 100 is acquired (S41). Then, the control unit 11 determines whether or not a counter Ci associated with a predetermined area including the position represented by the vehicle position information (position information of the in-vehicle radio device 100) is set. (S42). If the counter Ci associated with the region is not set as such (NO in S42), the control unit 11 has a predetermined area centered on the vehicle travel position (for example, the host vehicle travels). A counter Ci (initial value = 0) corresponding to a predetermined distance before and after the vehicle traveling position on the road is set (S43). Then, the control unit 11 increments the set counter Ci by +1 (S44: autoselect process counting means). When the counter Ci associated with the area of a predetermined area including the position represented by the vehicle position information has already been set (YES in S42), the control unit 11 counts the counter Ci by +1. (S44: Autoselect processing counting means).

  The control unit 11 determines whether or not the count value of the counter Ci is greater than or equal to a predetermined value Co (S45). If the count value of the counter Ci does not reach the predetermined value Co (NO in S45), the control unit 11 selects a broadcast station from the selectable broadcast stations set in the autoselect process (S11). Is performed (S19). On the other hand, when the count value of the counter Ci has reached the predetermined value Co (YES in S45), the control unit 11 performs the same processing (S12 to S14) as described above to the vehicle status information (vehicle position information, (Acquired in S41), vehicle travel direction information, broadcast station information) is stored (registered) in the storage unit 14, and the setting of the counter Ci is canceled (S46). Then, the control unit 11 performs a process (S19) for selecting a broadcast station from the selectable broadcast stations set in the auto-select process (S11).

  Further, whether or not an operation for executing auto-select processing has been performed on the operation unit 12 (S10) and the situation of the host vehicle (travel position, travel direction, and currently selected broadcasting station) are stored in the storage unit. In the process of monitoring whether or not it matches the situation represented by the vehicle situation information stored in FIG. 14 (see FIGS. 7A and 7B) (S15, S16, S17), the situation of the host vehicle is stored in the storage unit 14 (S15: YES, S16: YES, S17: YES), the control unit 11 automatically executes auto-select processing as described above. (S18). Then, one broadcast station is selected from the selectable broadcast stations set by the autoselect process (S19).

  In the in-vehicle radio receiving apparatus 100 that performs processing according to the procedure shown in FIG. 8, when the own vehicle (the in-vehicle radio receiving apparatus 100 that moves together with the own vehicle) passes through a certain area, the auto is based on the operation at the operation unit 12. When the number of times the selection process is performed reaches a predetermined value Co, vehicle status information including vehicle position information indicating the traveling position of the host vehicle is stored in the storage unit 14. That is, only when the operation of the auto-selection process is frequently performed in an area where there is a road on which the user frequently passes (the predetermined number of times Co or more) in the own vehicle, the situation when the own vehicle passes through the area is represented. The vehicle status information is stored (registered) in the storage unit 14. Accordingly, when the situation of the host vehicle becomes a situation represented by the vehicle situation information stored in the storage unit 14 on a road with high usage frequency, the automatic selection process (S18) is automatically performed regardless of the operation of the operation unit 12. ) Is executed, storage (registration) of vehicle status information that is not frequently used in the normal time is prevented from being stored (registered), and processing for storing (registering) useless vehicle status information in the storage unit 14 is prevented. Can be prevented, and the storage capacity of the storage unit 14 can be saved.

  In each example described above, the vehicle status information when the autoselect process (S11) based on the operation on the operation unit 12 is executed is stored (registered) in the storage unit 14, but this is not limitative. Not. For example, vehicle status information (device status) indicating the status of the vehicle (the status of the in-vehicle radio receiving device 100 moving with the vehicle) on which the autoselect process (S18) should be executed in accordance with the operation of the operation unit 12 including the touch panel of the display unit 13. Information) can be registered in the storage unit 14.

  For example, as shown in FIG. 9, the user operates the operation unit 12 on the point Pi of the vehicle (M) to be subjected to autoselect processing on the road map displayed on the display unit 13 and the traveling direction Di at the point Pi. , The control unit 11 includes vehicle position information (position information) representing the designated point Pi (Xi, Yi), vehicle travel direction information (movement direction information) representing the designated travel direction Di, and Then, the broadcast station information representing the broadcast station designated by the operation of the operation unit 12 is stored in the storage unit 14 (see FIG. 4) as vehicle status information (device status information) (second device status information storage control means). Thereby, when the host vehicle (the in-vehicle radio receiving device 100 moving with the host vehicle) is in a situation represented by the vehicle status information (device status information) stored in the storage unit 14 by the operation of the operation unit 12. In addition, the autoselect process is executed regardless of the operation on the operation unit 12.

  In this case, if it is known in advance what kind of situation (vehicle situation information (apparatus situation information)) the own vehicle (the in-vehicle radio reception device 100) should execute, the auto-select process is performed. Which station is selected when the own vehicle (the in-vehicle radio receiver 100) travels (moves), and whether the reception quality is lowered and the autoselect process should be executed. If it is known in advance, the vehicle status information (including vehicle position information and broadcast station information) can be stored in the storage unit 14, so that the user performs the autoselect process while the vehicle is traveling. There is no need to perform the operation.

  In each example described above, the vehicle status information as information representing the status of the in-vehicle radio receiver 100 is vehicle position information, vehicle travel direction information, and broadcast station information, but is not limited thereto. The vehicle status information is not particularly limited as long as it can represent the status of the vehicle. Of the three pieces of information, the vehicle status information is a combination of two pieces of information including the vehicle status information. In addition, these three pieces of information may further include other information representing the vehicle status.

  Further, the present invention is not limited to the above-described in-vehicle radio receiver, but may be other types of in-vehicle broadcast receivers such as an in-vehicle television receiver. Moreover, the broadcast receiving apparatus according to the present invention may be, for example, a mobile terminal apparatus such as a smartphone equipped with an application that realizes a navigation function and a radio receiver function.

  As described above, the broadcast receiving apparatus and the processing method in the broadcast receiving apparatus according to the present invention do not particularly require a large amount of storage capacity, and do not require a large amount of storage capacity. And is useful as a broadcast receiving device mounted on a moving body such as a vehicle and a processing method in the broadcast receiving device.
